本発明によれば、限られたスペースで記録ヘッドを確実に押圧固定することにより位置決めすることができると共に、低コストで構成することのできるインクジェットプリンタにおける記録ヘッドの固定構造を提供することができる。   According to the present invention, it is possible to provide a recording head fixing structure in an ink jet printer that can be positioned by reliably pressing and fixing the recording head in a limited space and can be configured at low cost. .

以下、本発明の実施の形態について図面を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、インクジェットプリンタにおける記録ヘッドの取付け部の断面図であり、記録ヘッドを固定した状態を示す。図２はインクジェットプリンタにおける記録ヘッドの取付け部の平面図であり、記録ヘッドを取り外した状態を示す。   FIG. 1 is a cross-sectional view of a recording head mounting portion in an ink jet printer, showing a state in which the recording head is fixed. FIG. 2 is a plan view of the recording head mounting portion in the ink jet printer, showing a state in which the recording head is removed.

図中、１は記録ヘッドであり、図示下面は図示左右方向に沿って多数のノズルが配列されたインク吐出面１ａとされている。また、記録ヘッド１における図示左右の各側面１ｂ、１ｃには、上記インク吐出面１ａよりも若干上方位置にそれぞれ係止段部１１、１２が突設されていると共に、図示左側の側面１ｃにおいて、上記係止段部１２とインク吐出面１ａとの間に、後述するスライド部材３の先端と係合する係合部１３が凹設されている。   In the figure, reference numeral 1 denotes a recording head, and the lower surface in the drawing is an ink discharge surface 1a in which a large number of nozzles are arranged along the horizontal direction in the drawing. Further, on the left and right side surfaces 1b and 1c of the recording head 1, locking step portions 11 and 12 project from the ink discharge surface 1a slightly above, respectively, and on the left side surface 1c in the drawing. An engaging portion 13 that engages with a tip of a slide member 3 to be described later is provided between the locking step portion 12 and the ink discharge surface 1a.

２は記録ヘッド１の取付け板であり、プリンタ本体（図示せず）において記録媒体（図示せず）に対して適正な一定の距離を保つように配設されており、この取付け板２に記録ヘッド１を固定することで、記録ヘッド１のインク吐出面１ａが記録媒体に対して適正な距離を保って配置されるようになっている。   Reference numeral 2 denotes a mounting plate for the recording head 1, which is disposed in the printer main body (not shown) so as to maintain an appropriate constant distance from a recording medium (not shown). By fixing the head 1, the ink ejection surface 1 a of the recording head 1 is arranged at an appropriate distance from the recording medium.

取付け板２には、記録ヘッド１のインク吐出面１ａ側を挿通させ得るに十分な大きさを有する開口２１が形成されており、その一端側（図示右端側）の上面には、記録ヘッド１の一方の係止段部１１が嵌り込むことによって係合する係合爪２２が立設されている。この係合爪２２において記録ヘッド１の係止段部１１が嵌り込むことによって係合する面は、記録ヘッド１のノズル配列方向に沿う図１中のＸ方向の基準面とされる。   The mounting plate 2 is formed with an opening 21 having a size large enough to allow the ink ejection surface 1a side of the recording head 1 to be inserted, and on the upper surface of one end side (the right end side in the drawing), the recording head 1 is formed. An engaging claw 22 that engages when one of the locking step portions 11 is fitted is provided upright. A surface engaged with the engagement claw 22 when the locking step portion 11 of the recording head 1 is fitted is a reference surface in the X direction in FIG. 1 along the nozzle arrangement direction of the recording head 1.

なお、記録ヘッド１の各係止段部１１、１２の幅（図２における上下方向の長さ）は、取付け板２の開口２１の幅ｄよりも若干大きく形成されており、記録ヘッド１のインク吐出面１ａ側を上記取付け板２の開口２１に対して上方から挿通させた際、各係止段部１１、１２が開口２１の縁部上面に当接するようになっている。このとき記録ヘッド１の各係止段部１１、１２が当接する取付け板２の開口２１の縁部上面は、記録ヘッド１のインク吐出面１ａと垂直な方向に沿う図１中のＹ方向の基準面とされる。   Note that the width (the vertical length in FIG. 2) of the locking step portions 11 and 12 of the recording head 1 is slightly larger than the width d of the opening 21 of the mounting plate 2. When the ink discharge surface 1 a side is inserted from above into the opening 21 of the mounting plate 2, the locking step portions 11 and 12 come into contact with the upper surface of the edge of the opening 21. At this time, the upper surface of the edge of the opening 21 of the mounting plate 2 with which the respective locking step portions 11 and 12 of the recording head 1 abut is in the Y direction in FIG. 1 along the direction perpendicular to the ink ejection surface 1a of the recording head 1. The reference plane is used.

また、図中、３はスライド部材であり、取付け板２において係合爪２２の突設側の端部と反対側の端部に配設されている。   In the figure, reference numeral 3 denotes a slide member, which is disposed at the end of the mounting plate 2 opposite to the end of the engaging claw 22 on the protruding side.

スライド部材３は、取付け板２の下面において、平板部３１が挟着部材４との間で挟着されて支持されることにより、該取付け板２の開口２１内を、記録ヘッド１のインク吐出面１ａに平行な面に沿う図１中のＸ方向に沿う方向に平行に移動可能に設けられている。   The slide member 3 is supported on the lower surface of the mounting plate 2 with the flat plate portion 31 being sandwiched between and supported by the sandwiching member 4, so that the ink ejection of the recording head 1 is performed in the opening 21 of the mounting plate 2. It is provided so as to be movable in parallel with the direction along the X direction in FIG. 1 along the plane parallel to the plane 1a.

スライド部材３のＸ方向に向いた先端３ａは、記録ヘッド１の固定時に、記録ヘッド１の係合部１３内に嵌り込むことにより係合可能な先細り状に形成されており、該先端３ａからＸ方向と反対方向である図示左方向に行くに従って、次第に高さが高くなる比較的なだらかな傾斜面３ｂとされている。また、その傾斜面３ｂの後端は、比較的急な角度で斜め下方に下っており、後述するカム部材５が摺動する摺動面３ｃを形成している。   The tip 3a of the slide member 3 facing in the X direction is formed in a tapered shape that can be engaged by fitting into the engaging portion 13 of the recording head 1 when the recording head 1 is fixed. A relatively gentle inclined surface 3b whose height gradually increases as it goes in the left direction in the figure, which is the direction opposite to the X direction. Further, the rear end of the inclined surface 3b is inclined obliquely downward at a relatively steep angle to form a sliding surface 3c on which a cam member 5 described later slides.

５はカム部材であり、取付け板２に軸５１が回転可能に支持され、該カム部材５と一体に形成されたレバー６を人手で操作することにより、カム部材５を、軸５１を中心にして回転操作することができるようになっている。   Reference numeral 5 denotes a cam member. A shaft 51 is rotatably supported by the mounting plate 2, and the lever 6 formed integrally with the cam member 5 is manually operated, so that the cam member 5 is centered on the shaft 51. Can be rotated.

カム部材５は、レバー６を操作して記録ヘッドを固定した状態としたときに、カム部材の回転軸からスライド部材３の摺動面３ｃに下ろした垂線よりも下方で接するような形状とされる。   The cam member 5 is shaped such that when the lever 6 is operated and the recording head is fixed, the cam member 5 is in contact with the lower side of the perpendicular line drawn from the rotating shaft of the cam member to the sliding surface 3c of the slide member 3. The

このレバー６は、記録ヘッド１を固定する前の状態では、カム部材５を挟んで取付け板２の開口２１とは反対側に大きく倒れ込むように配置されている。具体的には、記録ヘッド１着脱時のインク吐出面１ａの後端側の動作線Ａ（図４参照）よりも開口２１とは反対側に大きく倒れ込むように設けられており、記録ヘッド１の着脱スペースを邪魔しないようになっている。また、このとき、スライド部材３も上記動作線Ａと交叉しないように、図示左方向に退避している。   The lever 6 is arranged so as to largely fall down on the side opposite to the opening 21 of the mounting plate 2 with the cam member 5 in between before the recording head 1 is fixed. Specifically, the recording head 1 is provided so as to be largely tilted to the opposite side of the opening 21 from the operation line A (see FIG. 4) on the rear end side of the ink ejection surface 1a when the recording head 1 is attached / detached. It is designed not to disturb the removable space. At this time, the slide member 3 is also retracted in the left direction in the figure so as not to cross the operation line A.

カム部材５は、取付け板２の開口２１内において、上記スライド部材３の摺動面３ｃの側に位置しており、該カム部材５と開口２１の端部との間には弾発部材７が介設されている。弾発部材７は、ここでは金属薄板７１の先端をＵ字状に曲げ加工してなる板ばねを用いているが、特に限定されず、例えば、ゴム等の弾性を有する部材を用いて、カム部材５に対して弾発力を作用させるようにしてもよい。   The cam member 5 is located on the sliding surface 3 c side of the slide member 3 in the opening 21 of the mounting plate 2, and the elastic member 7 is interposed between the cam member 5 and the end of the opening 21. Is installed. Here, the elastic member 7 uses a leaf spring formed by bending the tip of the thin metal plate 71 into a U shape. However, the elastic member 7 is not particularly limited. An elastic force may be applied to the member 5.

この弾発部材７は、記録ヘッド１を固定していない時には、カム部材５と接してはいるものの、該カム部材５に対して実質的に弾発力を作用させておらず、図１に示すように、記録ヘッド１を固定している時に、カム部材５に対して弾発力を作用させ、カム部材５の表面が当接するスライド部材３の摺動面３ｃを記録ヘッド１に向けて押圧する。   The elastic member 7 is in contact with the cam member 5 when the recording head 1 is not fixed, but does not substantially apply an elastic force to the cam member 5, and is shown in FIG. As shown, when the recording head 1 is fixed, a resilient force is applied to the cam member 5 so that the sliding surface 3c of the slide member 3 with which the surface of the cam member 5 abuts faces the recording head 1. Press.

次に、記録ヘッド１の着脱操作について説明すると、図３に示すように、レバー６が大きく倒された状態で、記録ヘッド１を取付け板２の開口２１に対して、その先端側（側面１ｂの側）から斜め右下方に向けて挿通させ、係止段部１１を取付け板２の係止爪２２と係合させた後、図４に示すように、後端側の係止段部１２を開口２１の縁部上面に当接させ、記録ヘッド１を各係止段部１１、１２によって、図１に示すＸ方向及びＹ方向の各基準面に突き当てる。   Next, the operation of attaching and detaching the recording head 1 will be described. As shown in FIG. 3, the recording head 1 is moved to the front end side (side surface 1b) with respect to the opening 21 of the mounting plate 2 in a state where the lever 6 is largely tilted. 4), the locking step portion 11 is engaged with the locking claw 22 of the mounting plate 2 and then, as shown in FIG. Is brought into contact with the upper surface of the edge of the opening 21, and the recording head 1 is brought into contact with the reference surfaces in the X and Y directions shown in FIG.

この記録ヘッド１を取付け板２の開口２１に挿通する際、レバー６及びスライド部材３のいずれも記録ヘッド１の動作線Ａと交叉していないため、記録ヘッド１の装着作業の邪魔となることはない。   When the recording head 1 is inserted into the opening 21 of the mounting plate 2, neither the lever 6 nor the slide member 3 intersects with the operation line A of the recording head 1, which obstructs the mounting operation of the recording head 1. There is no.

記録ヘッド１が、図４に示すように取付け板２に取付けられた後、レバー６を記録ヘッド１側に向けて引き起こすようにして回転させると、レバー６と一体となって、カム部材５が軸５１を中心にして図示時計方向に回転し、その表面に当接しているスライド部材３の摺動面３ｃを図示右方向に向けて押圧する。   When the recording head 1 is attached to the attachment plate 2 as shown in FIG. 4 and then rotated so as to cause the lever 6 to move toward the recording head 1, the cam member 5 is integrated with the lever 6. It rotates in the clockwise direction in the figure around the shaft 51, and presses the sliding surface 3c of the slide member 3 in contact with the surface thereof in the right direction in the figure.

スライド部材３は、摺動面３ｃがカム部材５に押圧されることにより、記録ヘッド１のインク吐出面１ａに平行な面上を該記録ヘッド１側に向けて移動し、その先端３ａが記録ヘッド１の係合部１３内に嵌り込んで係合しつつ、記録ヘッド１をＸ方向の基準面となる係合爪２２に向けて押圧し、記録ヘッド１をこの基準面に対して位置決めする。   When the sliding surface 3c is pressed by the cam member 5, the slide member 3 moves toward the recording head 1 on the surface parallel to the ink ejection surface 1a of the recording head 1, and the tip 3a of the sliding member 3 is recorded. The recording head 1 is pressed toward the engaging claw 22 serving as a reference surface in the X direction while being fitted in and engaged with the engaging portion 13 of the head 1 to position the recording head 1 with respect to this reference surface. .

また、スライド部材３の先端３ａは、図５に示すように、傾斜面３ｂと対象的な傾斜面３ａ1を有しており、記録ヘッド１の係合部１３の下部の段部１３１と当接し、カム部材５によって更に押圧されることで、この傾斜面３ａ1が記録ヘッド１をＹ方向にも押圧し、記録ヘッド１を取付け板２の縁部上面の基準面に対しても位置決めする。これにより、記録ヘッド１はインク吐出面１ａに垂直な方向にも押圧及び位置決めされる。 Further, as shown in FIG. 5, the tip 3 a of the slide member 3 has an inclined surface 3 b and a target inclined surface 3 a 1. In contact with and further pressed by the cam member 5, the inclined surface 3 a 1 presses the recording head 1 in the Y direction and positions the recording head 1 with respect to the reference surface on the upper surface of the edge of the mounting plate 2. . As a result, the recording head 1 is also pressed and positioned in the direction perpendicular to the ink ejection surface 1a.

記録ヘッドが解除状態のときに、カム部材５とスライド部材３の摺動面３ｃとの接点は、図６（ａ）に示すように、軸５１からスライド部材３の摺動面３ｃに向けた垂線ａよりも上方の位置であるため、弾発部材７の弾発力によりカム部材５がスライド部材３を押圧する力の反作用で、カム部材５には反時計方向に回転する力が作用する。   When the recording head is in the released state, the contact point between the cam member 5 and the slide surface 3c of the slide member 3 is directed from the shaft 51 to the slide surface 3c of the slide member 3 as shown in FIG. Since the position is above the perpendicular line a, the cam member 5 is counteracted by the force by which the cam member 5 presses the slide member 3 by the elastic force of the elastic member 7, and a force that rotates counterclockwise acts on the cam member 5. .

一方、図６（ａ）の状態からレバー６を回転することにより記録ヘッドを固定状態とすると、図６（ｂ）に示すように、カム部材５によってスライド部材３を最も押圧する垂線ａと同一位置を乗り越えて、垂線ａよりも下方の位置で当接する。このとき弾発部材７の弾発力によりカム部材５がスライド部材３を押圧する力の反作用により、カム部材５には時計方向に回転させるような力が作用する。カム部材５に時計方向の回転力が作用する。図６（ｂ）の状態は、レバー６を強制的に操作しない限り、カム部材５の図示反時計方向の回転は阻止される。これにより、レバー６はロック状態となる。   On the other hand, when the recording head is fixed by rotating the lever 6 from the state of FIG. 6A, the perpendicular line a that most presses the slide member 3 by the cam member 5 is the same as shown in FIG. 6B. It overcomes the position and abuts at a position below the perpendicular line a. At this time, due to the reaction of the force with which the cam member 5 presses the slide member 3 due to the elastic force of the elastic member 7, a force that rotates the cam member 5 in the clockwise direction acts. A clockwise rotational force acts on the cam member 5. In the state shown in FIG. 6B, the cam member 5 is prevented from rotating counterclockwise unless the lever 6 is forcibly operated. As a result, the lever 6 is locked.

本実施形態では、カム部材５及び弾発部材７によってスライド部材３の押圧動作と共に、このようにレバー６のロック動作を兼ねているため、ロック機構を別途設ける必要がなく、部品点数を削減でき、低コスト化を図ることができる。   In the present embodiment, since the cam member 5 and the resilient member 7 serve as both the pressing operation of the slide member 3 and the locking operation of the lever 6 in this way, it is not necessary to separately provide a locking mechanism and the number of parts can be reduced. Cost reduction can be achieved.
